KINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a spline drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes. Our variety of Down the Hole (DTH) bits is manufactured using high quality materials to provide you with a fine balance between penetration capability and bit life.
Features:
1)High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance
2) Accurate dimension of thread perfectly matches the rock drill
3) Work reliable and very cost-effective
